Application filed September 20, 1926.

This invention aims to provide novel means for connecting a truss pad to a post or standard in such a way that the pad may be rotated on the standard, and slid freely on the standard, longitudinally of the standard, novel means being provided for holding the pad in place on the standard.

It is within the province of the disclosure to improve generally and to enhance the utility or devices of that type to which the invention appertains.

lVith the above and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

In the drawings Figure 1 shows in perspective, a device constructed in accordancewiththe invention;

Figure 2 is a composite perspective view wherein the parts are separated;

Figure 3 is a sectional view taken through the post or standard;

Figure 4 is a cross section on the line 44 of Figure 3;

Figure 5 is a View like Figure 4, but showing a modification.

The truss pad 1 includes a back plate 2 having a hub 3 provided with a smooth circular opening 4 wherein a post or standard 5 is mounted to slide freely, lengthwise, and to rotate freely. The standard 5 has longitudinal ribs 6 defining longitudinal grooves 9. A clamping device 7 is provided, and the same may be a screw, threadedinto the hub 3, the inner end of the screw 7 being engaged as shown at 8 in one of the grooves 9 between the ribs 6.

The standard 5 has a head 10 cooperating with an arm or other support 11 that is provided with a slot 12 wherein a screw 14 is adjustable, the screw 14 being threaded into the bore 15 of the standard 5, and including a head 16 which clamps the arm 11 against the part 10, the head 16 of the screw being equipped with a pivoted bail 17 or the like, whereby the screw 14 may be adjusted in and out.

\Vhen the screw 7 is retracted, so that its Serial No. 136,562.

inner end is not engaged, as at 8, in one of the grooves 9, of the standard 5, the standard 5 may be shifted freely, in the direction of its length, in the hub 3, and the standard 5 i also can be rotated freely in the hub 3. After the standard 5 has arrived at the proper position with respect to the hub 3, the standard may be held in its adjusted position, by advancing the screw 7 until its inner end is engaged as at 8 in one of the grooves 9 of the standard 5. The construction is such that the pad 1 may be made to exert more or less pressure on the rupture, as occasion may demand.

The construction of the standard 5 with respect to the hub 3 has many advantages over a form wherein the standard is threaded into the hub. In the device forming the subject matter of this application, the rotary adjustment of the truss pad 1 on the standard 5 is independent of the adjustment of the truss pad lengthwise ot' the standard 5. The operator can move the truss pad 1 lengthwise of the standard 5 without rotating the truss pad on the standard; he can rotate the truss pad without shifting it longitudinally of the standard; and he can both rotate the truss pad on the standard and shift the truss pad len thwise of the standard, the parts being held, in any event, when the screw 7 is advanced into one of the grooves 9. i i

In Figure 5, parts hereinbefore described have been designated by numerals previously used, with the sulfix a The modification consists in omitting the longitudinal grooves 9 of Figure 4 from the standard 5 of Figure 5.

hat is claimed is 1. In a device of the class described, a truss pad provided with a hub having a smooth bore, a standard rotatable in the bore and slidable longitudinally in the bore, the standard being provided with circumferentially spaced longitudinal grooves, a clamping device movable in the hub and adapted to be engaged in any of the grooves, a support, and means for assembling the standard with the support.

2. A truss pad having a smooth bore, a standard rotatable in the bore and slidable longitudinally in the bore, the standard having longitudinal'grooves, and a screw threaded into the pad and adapted to be received in any of the grooves, to prevent the standard from rotating in the bore and and a clamping device movable in the hub to prevent the standard from moving longiand engaging the standard. tudinal'ly in the bore; In testimony that I claim the foregoing 10 3.
